Whe you export a stl file from Pro-E or solidworks, wat does the file contain?

x,y cordinates of vertices etc or what?

Wikipedia said:
An STL file describes a raw unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system.

I have an STL on my machine right now but it was exported INTO Pro-E. Like ME mentioned, it is a collection of facets.
 
So just a number of trianlges with different coordinates?...


Okay...

Thanks,

I was looking into making a program where it recognises the faces of Basic shapes... So it could be done...
